Abstract
Abstract There is a need to better understand well conditions during gravel pack completions and during production through a gravel pack. The sensors that are used to determine the conditions at the actual interface between the gravel pack and the production interval are located directly on the gravel pack assembly. This allows for the most accurate and timely understanding of the interface conditions. Sensors along the length of the gravel pack can provide real time bottom hole pressure and temperature readings. Other sensors could provide information on flow rate of fluids produced as well as density measurements. Thus, during completion, the sensors can provide information on the effectiveness of gravel placement. During production, the sensors could provide instantaneous information on dangerous well conditions in time to minimize damage to the well equipment.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
60 words
A device for use in the production of hydrocarbons from wells, said device comprising: a sand screen having a connection at one end for attachment to a tool string for a borehole; a conductor that is routed through a hollow member of said sand screen and connected to carry a signal across at least a region of said sand screen.
Claim 2
Independent Claim
60 words
A device for use in the production of hydrocarbons from wells, said device comprising: a sand screen having a connection at one end for attachment to a tool string for a borehole; a conductor that is routed through a hollow member of said sand screen and connected to carry a signal across at least a region of said sand screen.
Claim 3
Dependent Claim
15 words
The device of claim 1 , wherein said conductor couples a battery to a sensor.
Claim 4
Dependent Claim
17 words
The device of claim 1 , wherein said conductor couples a surface power source to a sensor.
Claim 5
Dependent Claim
20 words
The device of claim 1 , wherein said conductor is routed through a substantially hollow spacer in said sand screen.
Claim 6
Dependent Claim
27 words
The device of claim 1 , wherein said conductor is routed through a substantially hollow wire that is circumferentially wrapped around a mandrel to form said screen.
Claim 7
Independent Claim
54 words
A method of conducting a signal across a sand screen that is part of a gravel pack, comprising the steps of: running a conductor through a hollow element of said sand screen; attaching said gravel pack to a tool string; running said tool string down a borehole; and sending a signal through said conductor.
Claim 8
Independent Claim
54 words
A method of conducting a signal across a sand screen that is part of a gravel pack, comprising the steps of: running a conductor through a hollow element of said sand screen; attaching said gravel pack to a tool string; running said tool string down a borehole; and sending a signal through said conductor.
Claim 9
Dependent Claim
28 words
The method of claim 6 , wherein said hollow element of said sand screen is a wire that is circumferentially wrapped around a mandrel of said sand screen.
Claim 10
Dependent Claim
31 words
The method of claim 6 , wherein said hollow element of said sand screen is a spacer that holds a circumferentially wrapped wire away from a mandrel of said sand screen.
Claim 11
Dependent Claim
14 words
The method of claim 6 , wherein said conductor carries power to a sensor.
Claim 12
Dependent Claim
15 words
The method of claim 6 , wherein said conductor connects a sensor to a microprocessor.
